To all whom'z't-may concern.'

Be it known that I, JoHN Q. SmMAN, a citizen of the United States, and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Autographic Registers," of which' the following is a full, clear, and exact description, reference being had to the accompany' g drawing, forming part ofv this specification.

My invention relates to autographic registers, particularly of the type wherein paper is fed by an operating handle, over a tablet or writln table, and past a tearin blade a ainst wich the used strips may torn o In registers of this type, it has never been possible in the past so far as applicant has knowledge, to mount the registerl Hush in the top of a desk so that it is out of the way except when it is to be used, and when in use has the same writing surface as has the desk in which it is mounted.

It is accordingly one of the objects of my invention to provide an autographic re 'ster which has all of its members accessle from the top of the register, including the operating member for positively feeding the paper and the lid and tablet top, together with the locks therefor, giving access to the insideof the register.

In autographic re ters employing the sprocket feed toget er with perforated 1t is necessary to have a form of stripper which lifts s away from the feedin sprocket and dlrects them properly beneat the cutting or severing edge against which the used portions areto be`torn od' of the continuous strip. It is my object to provide a strip er late which very effectively serves t e a ove function, and also which combines two functions so as to provide a tablet top. It is also my object to so construct the stripper portions of this plate, that they prevent all chances of catching of the paper strips on the edge of the plate and the consequent fouling and crimpin of the strips as they are fed from the mac ine.

'Ihese objects I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

Flg. 4 is a top plan view of the register I with the lid broken away to show the said stripper and tablet top. at;

Fig. 5 is a detail plan view of thel'stripper portion of said tablet top.

The register has sides 1, l, and a top lid 2 which has a suitable engagement wit the lower ends of the register sides. There need be no end walls tothe casing as the register is to be sunk so that its top is Hush with the surface of a desk or table top 3. The lid of the register is caught at the upper end of the register by means of spring latches 4, which automatically yield to downward pressure of the lid and then spring into engagement with the lugs 5, 5, at the two ends of the tearing blade portion 6.of the said top. In an upstanding housing 7, just behind the tearing blade portion of the top, is suitably mounted a friction roll 8 that serves to hold the paper down against the feed roll, to be hereinafter described, said friction roll being lifted out of frictional engagement during the feeding of the paper, by means not shown and which comprise no part of this lnvention.

The feed roll 9 has the sprocket teeth 10 which engage in perforations evenly spaced along the edges of the paper strips 11. rIhe roll has a pinion 12 on its shaft, said pinion being located on the left side of the machine outslde of the casing. An idler pinion 13 meshes with this pinion 12.

Mounted loosely on a stud in the side of the machine is a gear 15 which meshes with the pinion 13 and thereby actuates the feed roll. Integral or connected tothe large pinthe ratchet loosely on the stud is "a Hat handle 17 which carries a spring ,pawl 18 for engagement with the ratchet. 'Ibis handle isthin'enou h to take up but little room alongsideof t e machine, and accordingly the machine may/ be set into the interior of a desk, or below the top of a table, and the handle allowed to extend up along the side. of the machine.

A-stop 1 9 is' mounted on the casing-of the machine for the handle, and the handle is provided with a further stop for its operatof-the register in ion is a ratchet 16 and mounted outside ofiro p ing movement as follows. Un the shaft of the feed roll is mounted a cam disk 20 having a flat edge portion 2l. The handle has a cam portion 22, which presents a contact member which will evenly engage the edge 21 of the cam. The ratchet and the pawl on the handle are so positioned that when the handle is against its stop 19 the pawl will be in engagement with one of the ratchet teeth, and the complete swinging forward of the handle will cause the ratchet to move two spaces, that is to say, the distance of two-teeth. The ycam disk is so positioned that this movement will bring the two contact portions above mentioned into engagement with each other at the end of such motion, and the pinions are so geared that this movement will accomplish one complete rotation of the sprockets so as to feed one designated section of the paper past the tearing point. Thus the handle serves as an overthrow preventer for the feed roll so that it can make but one complete movement at a time, the said handle being a positive stop. rlhe .handle will always upon one complete movement from its initial to its final position make one complete feed of a paper section. Some other form of stop and overthrow preventer could be devised which would not depart from the spirit of my invention, and the cam disk is merely the preferred form. The fact that the cam disk is connected direct to the feed roll causes not only the prevention of overthrow' of the roll but also causes an adjustment of the paper at the end of the stroke and thus an accurate tearing o.

If desired, some form of spring could be secured to the handle to cause it to move clear back to its initial position whenreleased after its stroke. Such mechanism is not shown as it is not necessary tothe operation of the machine.

The tablet top and stripper plate .comprises a flat plate 23 of `suitable material, which seats on lugs 24C extending inwardly from the side of the casing, and is held in place by bringing the lid down over the top of the machine, so that it bears on said plate. The plate is exposed through the lid in the usual manner in such machines, and at the upper end of the plate it is cut away as follows: The transverse cut 25 is made not quite the len h of the feed roll between the toothed mem ers on each end, so as to partially expose the roll. This cut is only wide enough to allow the upper portion of the roll to extend between the two transverse edges 26 of the cut, and these edges are beveled so that they/will allow the roll to move without friction against the plate. Thus the parts may be so positioned that there is a perfectly level space for the paper to pass over, wlth the roll extending up ush with the surface of the tablet top plate,

for frictional engagement with the paper.

tween the sprockets and the main portion of the roll so that the plate 23 will extend past the inner faces of the two toothed or sprocket members as at 26m. llt will be understood that this cut 25 therefore allows the middle part of the roll only to contact with the paper.

idlso cut in the plate at each end of the transverse cut, are two independent longitudinal slots or cuts 27, 27, adapted to just clear the sprocket teeth members, and allowing the teeth to extend into contact with the perforations in the paper. The toothed portions are surrounded by the plate at all sides, because of the limited width of the cut 25. lf some means interior of the machine is emplo ed to raise the roll 8, a cut or slot' would ave to be formed outside of the slots 27 "to allow this to pass through the plate 23. its this feature of controlling the friction is not part of the invention herein, it is omitted in the plate 23 as well as elsewhere in the drawings.

'lhus there is provided a simple fo of stripper which serves not only asa stripper from the toothed members, but also as a stripper from the feed roll and one which provides practically a complete holding of the paper out of jamming or catching in dll tev

the feeding devices, while at the same time its lill

a member. Thus in the desk type of reg I ister herein developed, the stripper plate has here the additional advantage of bg capablo of a setting into the register from the v top.

ll do not wish to be limited in the claims that follow to the exact structure described in the foregoing s ecicat'ion as the description refers but to t e preferred fo of my invention; on the contrary l wish to be entitled to the full scope of the we of equivalents in the construction of\my claims. Also lI do not wish to be limited in my claims because of i time to appreciate the i 1li use l i l w ess of y invention, as l intend it to be d the future in any manner that may i;

iat

Lacasse be economical and convenient, and that mere mechanical changes necessary to adapt it to future uses be fully included in the scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an autogra hic register, a casing therefor, a toothed ceding means for paper stri s, a roll for carrying said means, and a com ined tablet top and stripper plateadapted in one piece to be set into the casing, and cut away around the roll and the toothed feeding means.
